On the trunnion'end 'lll of the beam 68 is pivotally mounted as at l2 the brake headl with its associated brake shoe 16 and, likewise, at the pivotal point 12, is connected the lower end of the hanger 18 providing support for the rigging intermediate the wheels at this end of the truck, the upper end of said hanger being pivotally connected as at 80 to the bracket 82 integrally formed with the transom I0.

The upper end of the live truck lever 48 is pivotally connectedras at 84 to the pull rod 86, the opposite end of said pull rod having a pivotal connection as at 88 to the dead horizontal lever 9U, said dead horizontal lever extending through the opening 96 formed in the side frame 2 and being fulcrumed intermediate its ends as at 52 from the bracket 94 integrally formed on the truck frame at the juncture of the transom l5 with the side frame 2. The outer end of the horizontal lever 9i) is pivotally connected as at 93 to the clevis means EGB, the opposite end of said clevis means being pivotally connected as at EQ2 to the upper end of the cylinder lever |54, the lower end of said cylinder lever having a pivotal connection as at |56 to the pull rod 5G25. Intermediate its ends, the cylinder lever m4 is pivotally connected as at to the piston ||2 of the power means H4, said power means being secured to the bracket l (Figure 3) as by means of rivets l i8, said bracket being integrally formed on the side frame 2.

The pull rod |08 extends below the projecting end I4 of the load carrying member or center bolster and at its opposite end is pivotally connected as at l2@ to the lower end of the slack adjuster lever 22, said slack adjuster lever |22 being pivotally and adjustably connected at a point intermediate its ends as at |23 to the automatic slack adjuster |25 secured to the bracket |21 integrally formed with the side frame 2 as by the rivet means |23. The upper end of said Ltrunnion end |54 of the brake beam |52 is pivothanger being pivotally connected as at |64 from slack adjuster lever |22 has a pivotal connection as` at |24 to the clevis means |26, the opposite end of said clevis means having apivotal connection as at E28 to the dead horizontal lever |35), said horizontal lever |35 extending through the opening |32 provided in the side frame 2. At a point intermediate its ends, the horizontal lever |36 is fulcrumed in said opening as at |34 to the bracket |35 integrally formed on the truck frame at the juncture of the side frame 2 and the transom Si. The inner end of the horizontal lever |35 is pivotally connected as at |38 to the pull rod |43 and the opposite end of said pull rod is pivotally connected as at |42 to the upper end of the live truck lever |44. At a point intermediate its ends as at |45, the live truck lever |44 is pivotally connected to the fulcrum |48 which is secured on the offset end |50 of the brake beam |52 as by means of rivets |53. On the ally secured the brake head |56 with its associated brake shoe |58 and, at the same pivotal point, as at |55 is secured the lower end of the supporting hanger |52, the upper end of said the bracket integrally formed with the truck frame adjacent the juncture of the end rail 4 with the side frame 2,

The lower end of the live truck lever |44 is pivotally and adjustably connected as at |65 to the pull rod |68, the opposite end of said pull rod being pivotally and adjustably connected as at Il@ to the lower endof the dead truck lever |12, the upper end of said dead truck lever having a pivotal connection as at |4 to the bracket |75 integrally formed on the transom 8. Intermediate its ends as at |18, the dead truck lever E12 is pivotally connected to the fulcrum |85, said fulcrum being secured on the offset end |32 of the brake beam |84. Support means for the beam |84 is provided in the form of the hanger |85, the upper end of which is pivotally secured as at |53 to the bracket 9D integrally formed on the transom 8 adjacent its juncture with the side In operation, actuation of the power means will cause the piston l l2 to move to the left (Figure 2) thus causing the cylinder lever |84 to rotate in a counter-clockwise direction about the pivot |55 at its lower end, and through the clevis means |10 causing the dead horizontal lever 90 to rotate in a clockwise direction about the fulcrum 92 intermediate its ends thus causing the pull rod 86 to move to the right and rotating the live truck lever i8 in a clockwise direction about the pivot 5i; at its lower end until the brake shoe 36 carried by the brake beam 26 is brought into engagement with the periphery of the adjacent wheel. Continued movement causes the live truck lever 48 to rotate in a clockwise direction about the pivot 45 intermediate its ends, thus moving the pull rod 52 to the left (Figure 2) and causing the dead truck lever 56 to rotate in a clockwise direction about its point o1 support 58 until the brake shoe 'l5 carried on the brake beam 58 is brought into engagement with the opposite periphery of said last-mentioned wheel. Continued movement of the power means will cause the cylinder lever |84 to rotate in a clockwise direction about the pivot |02 at its upper end thus moving the pull rod |08 to the left (Figure 2) and causing the slack adjuster |22 to rotate in a clockwisev direction about its point of support |23 on the slack adjuster |25. The clockwise rotation of the slack adjuster lever |22 through the clevis means |26 actuates the horizontal lever |30 which rotates in a counter-clockwise direction about the pivot |34 intermediate its ends and causes the pull rod |40 to move to the left. Movement of the pull rod |48 rotates the live truck lever |44 in a counter-clockwise direction about the pivot point |56 at its lower end until the brake shoe |58 carried on the brake beam |52 is brought into engagement with the periphery of the adjacent wheel. Continued movement causes the live truck lever |44 to rotate in a counterclockwise direction about the pivot |46 intermediate its ends, thus moving the pull rod |88 to the right (Figure 2) and rotating the dead truck lever |12 in a counter-clockwise direction about its pivotal point ofsupport |14 thus bringing the brake shoe |98 carried on the brake beam |84 into engagement with the `opposite periphery of the last-mentioned wheel.

Release of the power means causes the various parts to move vin directions reverse to those just described thus releasing the brakes and causing them to assume their normal inoperative position. It will be understood of course that in actual operation the movements of the various parts described take place substantially simultaneously and not successively, this means of description being used for purposes of simplicity.

It is to be understood that I do not wish to be limited by the exact embodiments of the device shown which are merely by way of illustration and not limitation as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
